Atmel-ISP Hardware

Atmel ATF15xx Family: ISP Devices User Guide
A switch block (SW2) containing four DIP switches is located on the top of the ISP
board. It is used as a socket selector. If you are programming using an 84PLCC
socket, DIP Switch 4 from this group must be in the OFF (down) position. If you
are using a daughter board, DIP Switch 4 from SW2 must be in the ON (up) position.
The requirement holds whether you are using either the Atmel-ISP cable or Byte-
Blaster/ByteBlasterMV cable.
Special features have been added to the ISP board (Rev. 3 or later) to support multi-
voltage (3V/5V) device programming. These include a power supply regulation circuit
that can supply either 3V or 5V supply voltage (V
CC) and a 3/5V header to change the
V
CC voltage value. Additional changes to the board include: a better power-on/off switch,
improved PC board layout of regulator near the 84-pin PLCC socket, battery connector
terminals that are directly soldered on the board and other changes.
To select the proper V
CC voltage, use jumper JP3 on the Atmel-ISP board (Rev. 3 and
later). If the left two jumpers are connected, V
CC will be set to 5V. If the right two jumpers
are connected, V
CC will be 3.3V.
Power to the Atmel-ISP board is supplied by either an Atmel 9V AC/DC adapter or a 9V
battery. Use the Atmel AC/DC adapter to power the board as some adapters may have
the power and ground connections reversed, which can damage the ISP board. If you
are using a different AC/DC adapter, make sure that the center pin of the socket
adapter is at 9V, as shown in Figure 4-1.

You can find the revision of the Atmel-ISP board by looking on the front of it just below
the prototype area and above the Q2 and Q3 labels. It is always recommended that you
use the latest revision of the Atmel-ISP board when programming Atmel devices.
If you are unsure which is the latest ISP board revision, contact Atmel PLD Applications.

Optional Features
on Atmel-ISP
Board Useful for
Prototyping
These features are not included in the Atmel-ISP board. The following components can
be soldered onto the ISP board in order to test functionality of specific Atmel ISP
devices.
LEDs: LED1 is used for the power supply and the other two (LED2 and LED3) are for
prototyping.
Crystal oscillator, 1 MHz (Y1)
Two momentary input switches (PBSW1 and PBSW2)
4-position slide switch that encodes to two inputs (SW1)
5 alphanumeric LED displays with drivers (DSP1 - 5)
A user prototyping area
One 84-pin PLCC programming socket
One 10-pin JTAG header
Signal breakout headers
